1 . Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39­year­old businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her seven­year­old daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”
The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.
The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.

2 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO₂ is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
1. _______, our world is becoming much smaller.

A．Because of the rise in pollution

B．Thanks to science development

C．Because the earth is being polluted day and night

3 . 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
There are thousands of coral reefs (珊瑚礁) in the world; Unfortunately, however, they are now in serious danger. More than one-third are in such bad shape that they could die within ten years.    1    Here are the three main causes discovered.
The first cause is pollution on land. The pollutants run with rainwater into rivers and streams, which carry the poisons into the ocean.    2    So they will be easily infected (感染) with diseases.
    3    Higher ocean temperatures kill the important food source (来源) for the coral—the algae, the tiny greenish-gold water plants that live on coral.    4    This process has happened more and more frequently in recent years.
The last factor contributing to the disappearance of coral reefs is people. People sometimes crash into reefs with their boats, breaking off large blocks of coral.    5    Moreover, some people even break coral off to collect for souvenirs since it is so colorful and pretty.

A．Global warming is another reason.

B．Many might not even last that long!

C．Divers who walk on reefs can also do serious damage.

D．Reefs provide a home for 25% of the fish in the ocean.

E．Chemicals from the poisons kill reefs or make them weak.

F．Steps must be taken now to stop over-fishing and pollution of the oceans.

G．When the algae die, the coral loses its color and it also dies in the end.

4 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.

Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

5 . Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost unavoidably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it is calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation (通货膨胀)is adjusted in order to take into account its mis­leading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total de­mand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long term health effects to nearby populations of animals, or people.___They___also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would block airflows’ natural speed which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pres­sure balance that is brought about by this current will be affected, and it is important to re­member that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without any resulting environmental damage, whatsoever, is impossible.

4. Which of the following shows the structure of the passage?

A．	B．
C．	D．

6 . When policy experts debate climate change solutions, they often talk about "a price on carbon." They are arguing about whether companies should pay when they put carbon pollution in the air. Proponents say that it's simple economics -- if it's free to pollute, you'll get a lot of pollution. Opponents claim it will raise the cost of energy that's produced from high carbon sources, like coal. But here's the secret that most people seem to be missing: There already is a price on carbon, and it's paid by the taxpayers.
Carbon pollution, like every other form of pollution, has an impact on the environment. Throwing waste into a river will cause the fish to die and the people who drink the water to get sick.   And when you produce carbon pollution, you get climate change -- sea level rise, stronger storms, severe droughts, damage to agriculture, and more.
All of those impacts cost money. Insurance rates go up when storms get more destructive. Taxes increase when cities have to rebuild bridges and roads. Military budgets go up when droughts and population changes cause conflicts. Not to mention impacts on agriculture and health care costs.
In other words, the price on carbon is what we all pay when there is no market force to limit the pollution that causes climate change. So the debate is really about who will pay that price -- the companies who are making a profit from the fossil fuels, or the taxpayers who pick up the cost now?
Right now, we have private profit and public cost. It's just like if we allowed every business to throw its garbage in the street because it's too expensive to have it moved away properly. Does it add a little bit to your dinner check to require that restaurants dispose of their trash properly? Sure. But it would be more expensive for you if the city had to clean the streets of their garbage every day. So just like we put a "price on garbage" we need a "price on carbon pollution."
Now, a "price on carbon pollution" can mean a lot of things. You could tax companies based on the amount of carbon pollution they produce, and return the money to taxpayers. You could put a limit on how much they can produce, thereby requiring them to invest in ways to conduct business in a less polluting way.
1. What do the policy experts argue about carbon pollution?

A．Whether the companies should pay for it.

7 . London used to be “foggy”（有雾的） for the same reason that cities like Beijing or Chongqing are “foggy” today. The “fog” was in fact smog（烟雾）, a mixture of smoke and fog．In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal（煤）that people burnt in their houses to keep warm during the winter. By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more “pea-soupers”.
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel（燃料）, like gas, is quite expensive.
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer “pea-soupers” in Beijing than there used to be.

C．The reasons of air pollution in London and Beijing are different.

8 . The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world.
These were the goals set out by the Shanghai Water Authority. With the city’s population expected to increase only slightly and the economy to boom by 2020, Chen Yin, and official with the water authority, said Shanghai’s water consumption will not increase from its present amount.
Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, “Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve.”
He said water saving will help keep the sustainable development of China’s economy.
Saving one cubic meter of water means saving the city’s infrastructure（基础设施）costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology.
“The aim is to arouse public awareness of the seriousness of water shortages,” Chen said. “The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water.”
Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city’s drinkable water, is nearing exhaustion.
The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water.
Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used.
At present, the city has 600，000 family toilets, each using 13 liters of water per flush. These are to be renovated（整修）to use only 9 liters of water per flush.
The authority is renovating the first 200 toilets for households – at a cost of 40 Yuan each.
In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation.
Another task the city is engaged in is the treatment of sewage（污水）to improve the water environment.
At present the city can only treat 44 percent of its daily 5.04 million tons of waste water. To meet the total demand, 27 more sewage treatment factories are to be established with an estimated investment of 18 billion Yuan.
1. People in Shanghai get their daily water mainly from         now.

10 . Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.
1. Doctors have long known that__________.

A．one may lose his hearing when he hears a terribly loud noise.
